Screenshot a HTML Page from Java Script
Say, I have a Web page with beautiful graphs and charts. I want that to be
saved as an Image. Simply to state, take a screen shot of the HTML document from Java Script .
The Solution mentioned below worked for me

See the Following code available in paste bin.

1. Require a Target <div>, where those contents are going to be converted as Image
2. Require the 3 JavaScript Files
<script type='text/javascript' src='http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js'></script>
<script type='text/javascript' src='http://kubilayerdogan.net/screenshot/js/html2canvas.js'></script>
<script type='text/javascript' src='http://kubilayerdogan.net/screenshot/js/jquery.plugin.html2canvas.js'></script>
3. On the Click Event,
function capture() {
$('#target').html2canvas({
onrendered: function (canvas) {
$('#img_val').val(canvas.toDataURL("image/png"));
var d=(canvas.toDataURL("image/png"));
document.getElementById("result").src=d;
}
});
}
Simply the <div> (id: target) tag contents are converted to Canvas.
4. Convert Canvas to Raw Image ( toDataURL()) will do
5. Load the Raw Image in the <img> tag. Note that in this example, "result" is the id of the <img> Tag. If you try with <div> tag, it will not work.
To load the Raw Image, I referred the following URL.
